							39Cleaning 
Maintenance
This section describes maintenance tasks such as cleaning the projector and 
replacing consumable parts.
Cleaning
You should clean the projector if it becomes dirty or if the quality of projected 
images starts to deteriorate.
Cleaning the Projector
Clean the projectors surface by wiping it gently with a soft cloth.
If the projector is particularly dirty, moisten the cloth with water containing a 
small amount of neutral detergent, and then firmly wring the cloth dry before 
using it to wipe the projectors surface. Then wipe it again with a soft, dry 
cloth.
Cleaning the Lens
Use a commercially-available air blower, or use a lens cleaning paper to 
gently wipe the lens.
Cleaning the Air Filters and Air Intake Vent
If dust collects on the air filter or the air outlet, it can cause the internal 
temperature of the projector to rise, and this can lead to problems with 
operation and shortening of the optical engines service life.
It is recommended that you clean these parts at least once every three 
months. Clean them more often than this if using the projector in particularly 
dusty environments.
c
Do not use volatile substances such as wax, alcohol or thinner to clean 
the projectors surface. These can cause the projector to warp and make 
the coating finish peel off.
c
Do not rub the lens with harsh materials or subject the lens to shocks, as 
it can easily become damaged.
p
If the air filters are broken or if the warning message reappears after 
they have been cleaned, they should be replaced. Replace with a new air 
filter. See “
Replacing the Air Filter” on page 44. 
						

							40Replacing Consumables 
Replacing Consumables
This section explains how to replace the remote control batteries, the lamp, 
and the air filters.
Replacing the Batteries
If delays in the responsiveness of the remote control occur or if it does not 
operate after it has been used for some time, it probably means that the 
batteries are getting low. Replace the batteries. Have two spare AAA-size 
alkali batteries ready to use when required.
1Remove the battery cover.
While pushing the catch of the battery compartment cover, lift the 
cover up. 
2Insert the batteries.
Check the positions of the (+) and (–) marks inside the battery holder 
to ensure that the batteries are inserted the correct way.3Replace the battery cover.
Press the battery compartment cover until it clicks into place.
Lamp Replacement Period
It is time to replace the lamp when:
 The message Replace the Lamp. appears on the screen when 
projection starts
 When the Lamp indicator is flashing orange
Catch
A message will be displayed.
